3M’s man at the EPA?
We published a story this morning in the Sunday Gazette-Mail about Robert M. Sussman, who was hired last month by Obama EPA Administrator Lisa Jackson to be one of her top advisers. Lawyers who represent folks in at least three states who are drinking water contaminated by C8 and similar chemicals are concerned about Sussman, […]

Minnesota: In 3M case, judge says PFCs don’t qualify as a nuisance
An enormous lawsuit over water is getting smaller. In a ruling Friday, a judge limited a lawsuit charging that chemicals manufactured by the 3M Co. polluted water and hurt Washington County homeowners. Washington County District Judge Mary Hannon ruled the chemicals — PFCs, or perfluorochemicals — found in drinking water cannot legally be considered a […]

EPA, duPONT agree to lower limit of PFOA in drinking water near W. VA. plant
CHICAGO (March 12, 2009) – U.S. Environmental Protection Agency has issued a consent order to E.I. du Pont de Nemours and Co. that sets a new action level for PFOA – also known as perfluorooctanoic acid, or C-8 – in drinking water for communities surrounding the company’s Washington Works facility in Parkersburg, W. Va. The […]

More evidence against C8
This week, I did a story for the Gazette about a new study that found exposure to the Teflon-production agent C8 could be damaging sperm and reducing sperm counts in humans. I failed to mention a key thing in that story — that the levels of C8 involved really weren’t that high. The most troublesome […]

C8 might damage sperm, study says
CHARLESTON, W.Va. — Men with higher levels of C8 and similar chemicals in their blood have lower sperm counts and fewer normal sperm, according to a new scientific study published this week. The study, published in the journal Environmental Health Perspectives, is believed to be the first to link exposure to perfluorinated chemicals, or PFCs, […]

Minnesota: More lake fish contain former 3M chemical
A former 3M chemical has been found in fish taken from more metro area lakes, including Cedar, Calhoun and Lake of the Isles in Minneapolis. The compound, known as PFOS, was measured at levels of concern in 13 of 22 lakes, mostly in bluegills, black crappies and largemouth bass. The Minnesota Pollution Control Agency (MPCA) […]

Environmental hazards and health risk of common liquid perfluoro-n-alkanes, potent greenhouse gases
Abstract This article aimed at introducing the main physical properties and commercial/industrial uses of common liquid perfluoro-n-alkanes (including perfluoropentane, perfluorohexane, perfluoroheptane, perfluorooctane, and perfluorononane) and the environment and health hazards posed by their toxic decomposition products (especially in hydrogen fluoride and perfluoroisobutylene) because these perfluorocompounds are potent greenhouse gases, which have been blanketed into the […]

EPA wanted tougher C8 limit, memo says
CHARLESTON, W.Va. — Federal government scientists originally sought a much tougher standard for the toxic chemical C8 than was included in a nationwide health advisory issued last month, according to an internal U.S. Environmental Protection Agency memo. More than three years ago, EPA staffers proposed that the agency rewrite a deal with DuPont Co. to […]

Minnesota: Consumption limit for Twin Lake fish
State officials Friday warned people to limit how often they eat fish caught from Twin Lake in Robbinsdale and Crystal. The lake has been found to have levels of a man-made perfluorochemical (PFC) in the fish similar to the higher levels previously measured in metro area lakes Calhoun, Elmo and Johanna, the state Health Department […]

Minnesota: PFOS contamination identified in fish from more metro area lakes
Twin Lake in Hennepin County (Robbinsdale-Crystal) has been found to have levels of a perfluorochemical (PFC) in the fish similar to the higher levels previously measured in lakes Calhoun, Elmo and Johanna. The PFOS (perfluorooctonate sulfate) levels in these fish place them in the one meal per month consumption category, given no impact from other […]
